-. serum... (01. 229-42) This invention relates to a box divisionor partition structur of a very novel, practical'type and by means of which the interior spac'e'ol a receptacle is divided into compartments. with the structure of my invention a paperboard box made from a single blank of paperboard or similar material, and which is of a greater length-than its width, may be made with a minimum-oi waste, and at the same time the top and the bottom of the box with the partition structure of my in vention within the box will each have two thick nesses of material over the entire area of the top and bottom.

It is an object and purpose of the present invention to provide a box partition structure for attaining the results stated, which is very readily and economically produced and easily assembled from a flat condition intov its useful operative condition.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view of the box partition structure of my invention,

Figs. 2 and 3 are plan views of the blanks of material from which the assembled partition structure of Fig. 1 are made, and

Fig. 4 is a longitudinal vertical section through a box in which the partition structure of my invention is enclosed.

Like reference characters refer to like parts in the different figures of the drawing.

The box partition structure of my invention includes two members or elements each made from fiat paper stock. One of said elements shown in Fig. 3 is a rectangular blank of paperboard material, transversely of which and midway between its ends is a rectangular section I, defined .at its side edges by scoring or bending lines 2,

and integral with which at each side edge is a second rectangular section 3 defined at the longitudinal edge thereof opposite the scored line I by a second and parallel scored line 4. The length of the material of the blank extends a short distance at each end beyond the scored lines 4, and midway between the side edges of the blank a longitudinal slot 5 is cut from each and substantially halfway through each of the sections 3, as shown. There is thereupon provided beyond the scored lines 4 two flaps I, one at each side of each of the slots 5. The width of the flaps 6 is substantially one-half of the width. of the section i.

The box partition structure is completed by a rectangular section of paperboard material in.

2 dicated at 'l which, in the disclosure shown, has spaced slots 8 cut therein upwardly from its lower edge approximately halfway to its upper edge. The slots 8 are spaced apart a distance substantially equal to the width of the bottom section I. In assembling the partition structure the sections 3 are turned upwardly about the scoring lines 2 making spaced parallel sides 3 connected with a bottom as shown in Fig. 1, and the flaps 6-- are turned inwardly toward each other. The cross-partition i is then assembled with the folded structure described by downward movement thereof into the slots 5, with the slots 8. of the member "lembracing the sides 3 from the ends of said slots 5 to the bottom I. This secures the vertical sides 3 in a relatively fixed parallel vertical relation to each other.

The length of the member I is substantially the inner dimensional length of a box in which the structure is to be placed, and the width of the blank shown in Fig. 3 is the inner width dimension of such box. Said box will have vertical ends a, from th upper and lower edges of which bottom flaps iii are turned inwardly at right angles extending toward each other; and from the sides or the box at both the upper and lower edges thereof, overlapping upper and lower bottom flaps H are turned inwardly, said flaps ll being of a width equal to one-half of the width of the box. Said box, preferably, will be of a width equal to twice the length of an inner top or bottom closure flap It. When the outside upper and lower flaps ii are turned inwardly toward each other their free edges will come together and may be held in closed position by adhesive tape or other suitable means. The flaps Ill reach substantially to the outer sides of the vertical sides 3 of the inner partition structure. The flaps 8 turned inwardly toward each other are in line with or in the same plane as the upper inner or end flaps it, while the bottom I isin the same plane as the inner lower or bottom flaps it. Thus there is over the entire surface at the bottom and at the top of the assembled structure two thicknesses of the paperboard material.

The structure described is very rapidly and economically produced and assembled and provides a novel, reinforced partition structure adapted to be used within outer containers in the manner described. The interior space of the box is divided into a number of compartments and two of such compartments will be closed at their upper ends by flaps l and havea bottom proand is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

1. In a structure of the class described, a member having a flat rectangular bottom. spaced vertical sides and fiaps adapted to extend inwardly toward each other at the upper edges of said sides, said flaps and vertical sides being slotted from the free longitudinal edges of "the fiaps transversely therethrough and through a portion of the width of said sides from the upper edges thereof downwardly for a distance, and a transverse member of rectangular shape having parallel vertical slots extending upwardly from its lower edges for a distance, said transverse member entering and being located in the slots of said flaps and vertical sides and, between the slots of said transverse member, extending to said rectangular bottom and at each end extending beyond the vertical sides of the first member.

2. A structure as defined in claim 1, said slots in the flaps and vertical sides of the first member being located substantially midway between the ends thereof.

said material sheet is foldable into a structure having a horizontal bottom, vertical sides and inwardly extending separated fiaps at the upper 10 edges of said sides, and a second member of,

-' fiat paperboard material of rectangular form having a width substantially equal to the width of the second mentioned rectangular sections of the first described member and twice slotted u from one longitudinal edge thereof substantially half the width, said slots being spaced from each other a distance substantially equal to the width of the first mentioned rectangular section of the first described member.

4. A structure as defined in claim 3, said slots in the first sheet of paperboard material extending from the ends thereof toward each other and being located in longitudinal alignment with each other and substantially midway between opposite 8. A box partition structure comprising. a 25 longitudinal edges of said sheet.

rectangular sheet of paperboard having a trans versely disposed rectangular bottom section between the ends thereof and located symmetrically with respect to said ends, an integral rectangular section extending from each side of said first mentioned rectangular section, there being bending lines between the adjacent edges of said first and second rectangular sections. and additional bending lines parallel to the first lines 5. A structure as defined in claim 4, the distance between the last mentioned bending lines of said first rectangular sheet of material and the adjacent ends thereof being equal substan- 6 tially to one-half of the width of the first mentioned rectangular section of said first member.
